Title: Ride with NEA 2005YU55
Post by frankuitaalst on 11/13/11 at 06:03:14

Took some time to make this animation (with my own integrator )
Viewpoint is a virtual camera just 2 km' s behind the asteroid 2005YU55 which made a clos pass to Earth some days ago .
The asteroid appears centered in the image , and the picture gives the direction of motion of the asteroid through our solar system .
So if a planet is right behind the asteroid it means the asteroid is just heading into the direction of the planet , ie the planet is in the "cross hair" .
The camera has an aperture of 160° wide .
The animation starts about 9 months before close approach .
One can see Earth-Moon coming into the view  from the left , slowly moving towards the path of the asteroid .
During the animation also Mercury (grey) and sun (yellow) appear from the left , as well as jupiter (orange) and mars (red ) . At a given time Jupiter and Eart-Moon appear to be iin conjunction as viewed from 2005YU55.
Towards the end of the animation Earth-Moon are behind the asteroid , then move further to the right , then turn back , while , at closest approach the asteroid flies above the Earth-Moon system .
Each frame is the animation lasts 1 day .
